Overview
Hecla Mining acquired the Fire Creek mine in July 2018. From that time, its production and financial results were included in the Nevada Operations Segment. In the second quarter of 2021, Fire Creek was placed on care and maintenance after processing the remaining non-refractory ore stockpile. Mine production at Fire Creek was suspended in the first half of 2021, and Hecla Mining is continuing studies of hydrology, mining, and milling. A restart of mining operations is contingent on sufficient exploration success and development. The Fire Creek deposit is a low-sulfidation, epithermal deposit with gold mineralisation occurring in high-angle north-northwest-trending structures within Miocene-aged basalts and andesites.
Production
Production overview - 2018: gold 2040 kg.
Processing
During 2021, revenue was generated from processing stockpiled non-refractory ore at the Midas mill and third-party processing of refractory ore.
Expansion
Fire Creek is part of Hecla's Nevada portfolio, which is undergoing a strategic review and reassessment in 2025 for priority reranking. The company's exploration program for 2026 has been significantly increased compared to 2025 due to positive results.

Expansion
In January 2026, the U.S. Forest Service approved a five-year plan of operations for the Greens Creek Surface Exploration Project. This project is aimed at testing existing mineralised targets and identifying new ones not accessible from underground operations, with the goal of increasing the project's reserve base and extending the mine life. This includes work on the expansion of the tailings facility, which is expected to increase capacity to 2045.

Overview
The Los Reyes Project is a development-stage project. A preliminary economic assessment (PEA) is underway and is expected to be completed by mid-2026. This assessment will evaluate various development scenarios, including both open pit and underground operations, to maximise margins and mine life.
Processing
The planned processing methods for the Los Reyes Project include both milling and heap leaching, depending on the ore characteristics. Metallurgical test work has been conducted to determine the expected recoveries for each processing method. For milled ore, gold and silver recoveries are estimated to be 95.6% and 81%, respectively. For heap leached ore, gold and silver recoveries are estimated to be 73% and 25%, respectively.

Production
The Phase 1 concentrator began operations in late 2025. The first sale of concentrate was completed to Northam Platinum in the fourth quarter of 2025. The concentrator is ramping up and is expected to reach approximately 80% of its nameplate capacity by mid-2026. It is initially processing lower-grade development ore, with higher-grade ore to be introduced in the second quarter of 2026.
Processing
The mine uses a concentrator to process ore. The Phase 1 concentrator has a milling capacity of 770,000 tonnes per annum (ktpa). Development ore is hoisted via Shaft 1 and stockpiled on the surface. The orebody is described as high-grade, thick, and flat-lying, which is suited to large-scale, mechanised mining. The platinum-to-palladium ratio is approximately 1-to-1.
Equipment
The mine's infrastructure includes multiple shafts. Shaft 1 is used for initial hoisting. Shaft 3 is expected to be operational by April 2026, increasing the mine's hoisting capacity five-fold to 5 million tonnes per annum. The larger Shaft 2 is being developed to support future expansions, with hoisting targeted from Q3 2028. The mining method is described as safe, mechanised, and highly productive bulk mining.
Expansion
The mine is being developed in multiple phases. Phase 1 commenced production in Q4 2025. Phase 2 development is underway and is targeted for completion in Q4 2027. This phase includes a new 3.3-million-tonne-per-annum (Mtpa) concentrator module, which will increase total processing capacity to 4.1 Mtpa. The Phase 2 expansion is expected to increase annual production to over 450,000 ounces of platinum, palladium, rhodium, and gold (3PE+Au), plus more than 30 million pounds of nickel and copper. A Preliminary Economic Assessment (PEA) has been completed for a potential Phase 3 expansion to 10.7 Mtpa. This would further increase annual production to over 1.0 million ounces of 3PE+Au, plus approximately 22,000 tonnes of nickel and 13,000 tonnes of copper.

Overview
The Lake Mackay Project is a large-scale, underexplored tenement package considered prospective for a range of deposit styles, including copper-gold-silver, nickel-cobalt-manganese, and orogenic gold. Exploration activities, including drilling, are ongoing. In May 2022, IGO and Prodigy Gold restructured their agreement, resulting in Prodigy Gold holding a majority interest in the gold tenements, while IGO retains the majority share of the base metal tenements. Recent exploration has focused on several prospects, including Phreaker (copper-gold), Arcee (gold), and Goldbug (gold). Drilling at the Phreaker prospect in 2022 and 2023 returned encouraging polymetallic results.
